: : : : Thank you all so much for the enlightening information, of course I still have to find an equivalent.
: : : : Thanks again. you never miss.

: : : Miri, here's another idea. Some cultures have stories of imaginary beings that do favors for people. For instance, there's a British tradition of a creature, something like a fairy, that visits at night and does the housework. If your culture has anything like a "good fairy" or a "helpful angel," that would work as an equivalent.

: Thank you Berg, you are most helpful. As I mentioned later, the ice cream has a meaning here, because of the way they cheat, using a popsicle stick. I cannot find a combinatin of the two: the allusion to the crime and someone who does good things. I have to stick to one side, either the popsicle thing or the good humor. Yes, one of this things you cannot translate perfectly.
: What do you think? which side has the upper hand?

: Thanks a lot, miri

: I think he is called the Good Humor Man because he uses the ice cream stick to alter the parking meter, not the fact that he alters his friend's meters also. Is this an American piece that you are translating, since Americans have long had a love/hate relationship with parking meters?
In the film "Cool Hand Luke," Luke is sentenced to hard time in prison with robbers and murderers, and all he did was cut the tops off parking meters while he was drunk.
